GAS-HEATER.

SPECIFICATION forming` part of Letters Patent No. 244,056, dated July12, 1881.

Application filed January 31, 1881. (No model.)

To all whom it may concern Be it known that I, CHARLES E. HEQUEM- BOURG,of Dunkirk, in the county of Chautauqua and State of New York, haveinvented certain new and useful Improvements in Gas- Heaters, of whichthe following is a specification.

The object of my invention is to provide a simple and efficientgas-heatin g device and meter combined; and it consists of a sphericalbulb of brass or other suitable material, one side of which is providedwith a small gasopening and a series of larger openings for air arrangedin a circle around the gas-opening, in combination with a tubulargas-burner connected to the bulb at the side opposite the airholes, andhaving a series of perforations of larger diameter than the gas-opening, and with a supplementary tube arranged within it, as will be moreclearly hereinafter shown by reference to the drawings, in which- Figurel is a vertical longitudinal section through the center of the bulb, theconnectingtube and coupling, and through the perforated gas-heater. Fig.2 is a side elevation of the heater complete. Fig. 3is a modifiedarrangement of the device. Fig. 4 is also a modified arrangement,showingtheperforated gas-heater arranged vertically and provided with aflame-spreading or heating plate at the top. Fig. 5 is a section throughline X X, Fig. 2, and Fig. 6 is a top view of Fig. 3.

A represents the bulb, into which the gas and air pass and combine inthe proportion suitable for combustion.

a is the gas-opening, which is made large enough to give out a certainnumber of cubic feet of gas per hour under a given pressurefor instance,an eighth of an inch gas-opening with two inches of water-pressure willgive out twenty-ve cubic feet of gas per hour, and a sixteenth of aninch gas-openin g will give out a proportionately less number of cubicfeet per hourunderthe same pressure. It will bereadily seen thatby thismeans the consumption of gas perhour can be easily calculated. Theair-openings a are arranged around the gas-opening a, and are muchlarger than the gas-opening, so as to let in sufficient air to form asuitable combination of air and gas to produce the required air as theyenter the bulb in the direction of the arrows to circulate andthoroughly mingle together, thereby producing a more perfect combinationof the gases, and consequently a better combustion than any other formof chamber. The bulb is connected by a screw, as shown, or by otherwell-known means, to a short tube, B, and the burner or gas-heating tubeB' is connected to the opposite end of the tube B by a coupling, b. Atthe end of the heater B is a cap, G, for closing it, and inside of thesame, at its forward end, is placed a short piece of smaller tubing, c',for the purpose of equalizing the flow of gas. .The burner B is providedwith a series of perforations, c, through which the combined gas and airpass While in operation.

`In Fig. l, D represents a portion of the connecting gas-pipe, and D isa stop-cock for admitting or shutting off the gas. The coupling bassists in preventing the heat from reaching the bulb. The air, as itenters the openings a', also helps to keep the bulb cool. This isanimportant feature, for the reason that if the bulb should becomeheated the conditions would be changed, so as to render the whole deviceuseless for the purposes designed.

In Figs. 3 and 6 1 have shown a modification of the device, having theburner B curved and set on a vertical tube connected to the horizontaltube by an elbow, F, so as to adapt it to a curved or circularfire-chamber or to an upright boiler or furnace.

Fi g4 also shows a modiiication, in which the perforated burner or tubeB is connected to the horizontal tube by an elbow, F, and having aplate, E', connected at the top, which acts as a cap, a heater, and avdevice for spreading the llame. This device, when in operation,produces a very perfect combustion, that gives out a clear flame, freeVfrom smoke and of intense heating power, and is therefore well adaptedfor heating stoves or furnaces, or for steam -boilers or other purposesrequiring a strong heat without smoke. In connecting it to astove orboilerifor other device to be heated, it is passed through a hole in thestove,'the hole being large enough to allow the coupling b to just passthrough, as shown by the portion IOO of a stove or furnace, E, in lFig.2, so that all the air it receives to combine with the gas for thepurposes of combustion must pass through the air-holes a.

In some eases the supplementary tube c' may be dispensed with, and, ifdesired, the short tube B may be a part of the bulb or made in one piecewith it; but the device as shown operates Well in practice.

I claim as my invention- The spherical bulb A7 provided with a chamber,A', gas-opening a, and air-openings a', in combination With a coupling,b, a perforated gas-h eatin g tube, B', and a supplementary tube,

o', arranged within it, as and for the purposes 15 specified.
